Answer 2

Step-by-step explanation:

Since, the children were born at the interval of three years ,let us assume their age as x, x+3,x+6,x+9,x+12.

given- the sum of five children is 50

therefore,

x+x+3+x+6+x+9+x+12 = 50

5x+30 = 50

5x = 50-30

5x=20

x=4

Hence, age of the youngest child is 4 years.
